The source for 'Web Browser Engineering', an open-access book by Pavel Panchekha and Chris Harrelson that teaches how web browsers work by building a basic but complete browser in Python. The repository contains the Markdown book text, a build pipeline to HTML, and chapter-by-chapter browser implementations (lab1.py through labN.py) plus unit tests.

Use cases

• learn how web browsers work internally
• build a simple browser from scratch in Python
• understand HTTP, HTML parsing, and CSS layout fundamentals
• study browser rendering, compositing, and scheduling
• use a textbook for a browser engineering course
• understand how JavaScript execution and the DOM work in a browser
• learn about browser security concepts like cookies, XSS, and CSRF

When to choose

• you want a hands-on, code-driven explanation of browser internals
• you are teaching or self-studying web browser engineering
• you want to incrementally build a working browser chapter by chapter
• you prefer free, open-access educational material with runnable code

When to avoid

• you need production-grade browser code or a real browser engine
• you want a reference manual for a specific browser like Chrome or Firefox
• you are looking for web development tutorials rather than browser internals
• you need a JavaScript-based browser implementation (the labs are in Python)
